WORK SUPPORT.

Application filed June 29,

To all whom it may concern:

Be it known that I, FRANCIS De (honour, a citizen of the United States, residing at Irvington, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Work Supports, of which the following is a specification.

This invention relates to work supports and more particularly to a work support or machine element to be used in conjunction with an abrasive wheel for finishing, truing, bevelling and shaping work.

Some of the objects of the invention are: to produce a device of the character mentioned which is thoroughly efiicientand effective for quickly and accurately finishing patterns and the like; to produce a device with which patternscircular in natureof different sizes may be finished and trued and in which provision is made for bevelling the peripheral edges of such patterns if desired. IVith these and other objects in view the invention resides in the particular provision,

' arrangement and combination of parts hereinafter more fully described and illustrated in the accompanying drawing, in which Figure 1 is a central longitudinal sectional view through the device of the present invention and showing the same applied for use.

Figure 2 is a horizontal sectional taken on the line 2-2 of Figure 1.

Figure 3 is a transverse sectional view taken on the line 38 of Figure 2.

Figure 1 is a transverse sectional view taken on the line 4-4lof Figure 2.

Figure 5 is a detached perspective view of one of the component parts of the work holder. i

In carrying the present invention into use, it is to be understood, that the device which forms the essential and principal part and a work table having pivotal movement are to be correlated, which work table, is arranged in juxtaposition with respect to an abrasive wheel, such for instance as a sand wheel having a grinding face.

The device is positioned upon thetable 10 which is pivotally mounted as at 11. A sand wheel 12 is arranged adjacent the device. The wheel 12 is mounted for rotation and is disposed so as to present a side face thereof with respect tothe device for the purposes spccified. The device will include a base member 13 having a rib or cleat 1-1 on the under side thereof, which is adapted view 1920. Serial No. 392,692.

to enter a groove, in the upper face of the table 10. A work holder 15 is arranged for ad ustment between plates 16 and 17, one or both of which may be removably attached to the base member 13. The inner longitudlnal edges of the plates 16 and 1'? are beveled as at 18, and with the upper face portion of the base member 13, these beveled edges 18 define a dove-tailed way. The work holder 15 consists principally of two component parts. The part 19 of the work holder consists of an elongated strip beveled along its longitudinal opposite sides so as to fit snugly within the angle formed by the beveled edge 18 of the plate 17 and the upper adjacent face of the base member 13 and to receive other parts to be hereinafter described to permit their relative movement with respect thereto in certain directions. The part 20 of the work holder 15 consists of a block beveled along its opposite side edges so as to be received in the space defined by the part 19, base member 13 and the plate 16. The part 20 is provided with a centering pin 21. The part 19 of the work holder is provided with a lateral extension or wing 22, which is provided with a screweye or the like 23. The helical spring 24 connects the screw 23 with the pin 21, and this spring has a normal tendency to hold the part 20 retracted against the wing 22 for a purpose to appear. It will be noted that the base member 13 is grooved as at to accommodate the spring 2 1 and that the groove extends the entire length of the base member 13. The work in hand to be finished, etc, will be arranged on the centering pin 21 which will be disposed at a proper distance from the grinding face of the sand wheel 12 so that'the work may be finished accurately.

In order to impart movement to the work or pattern to be finished, etc, there is provided a work actuator and supporting means therefor which is adjustable with relation to the part 20 of the work holder and its centering pin. The supporting means for the work actuator, among other things consists of amember 26 in the nature of an elongated plate, beveled along its opposite side as at 27 so as to snugly fit within the space defined by the part 19 of the work holder, the base member 13 and the beveled edge of the plate 16. The lIlQDllMJ 213 is provided with a stub shaft 28 and lug 29. On the stub shaft 28 is mounted a wheel 36 which engages the work and acts to rotate the same. member 26 is effected by an adjusting screw 30, one end of which engages the lug 29 and the free end thereof is provided with a hand wheel 31. The screw 30 is in threaded engagement with the member 32 which provides a support or bearing for the screw. A helical spring 33 has one end secured to a fastener 23%, secured to the base member and its opposite end is secured to a fastener 35 secured to the member 26. It will now be manifest that with a work actuator such as the wheel 36, movement may be imparted to the work 37, when the periphery of the wheel 36 is brought into contact with the periphery of the work 37, consequently the periphery of the work 37 will be presented to the grinding face of the sand wheel 12 in a manner to provide it with a: true circumferential face. It will also be understood that the work holder 15 is adjusted so that when the work 37 is arranged upon the centering pin 21, the spring 24 will hold the work in contact with the wheel 36. The' iortin member 26 is shown to be accomplished by the employment of the screw 30 which serves to move the member .26 in one direction while the spring 5:53 serves to retract the same as the screw is moved in the opposite direction. Such arrangement of parts permits the member 26 to be quickly adjusted but no limitation is necessarily made to such arrangement as one end of the screw 30 may be swiveled or otherwise turnably secured to the lug 29.

It will be manifest that inasmuch as the table 10 is mounted for pivotal movement, the fixture as well may be shifted in its entirety to permit of the bevelling of patterns.
